Definitions

  • the present invention refers to a voice conveying guide tube for headsets.
  • the voice conveying guide tube commonly known as a voice tube, is a hollow tube which allows the operator's voice to be carried from his mouth toward a microphone which is normally positioned inside an earpiece of the headset.
  • a ball joint between the voice tube and a support on the earpiece allows rotary movement of the voice tube and a telescopic joint allows translation of the voice tube.
  • the object of the invention is to solve the problems illustrated above, providing a voice tube for headsets that is practical, versatile, economical, easy to make and can be removably mounted on the headset so that it can be replaced as required.
  • the voice tube according to the invention provides a hollow tubular element which is assembled directly on the earpiece assembly of the headset without any articulated joint, such as a ball joint or a telescopic joint, being provided.
  • the tubular element is made of a suitable material which can be deformed by the operator. Said tubular element, once deformed, is able to maintain the desired shape of deformation. Thus the operator can bend the voice tube according to his own needs, directing it towards his own mouth and the guide tube maintains this position until the next deformation.
  • the voice tube is removably coupled to the earpiece element of the headset through pressure, and engagement and disengagement of the voice tube from the earpiece assembly of the headset is extremely simple for the user. In this manner, once the voice tube has been used, it can be disengaged from the headset and replaced with a new voice tube. Consequently the voice tube according to the invention fully satisfies the required hygienic standards.
  • the voice tube according to the invention can be produced and sold separately from the headset. Consequently a variety of voice tubes of different colours, obtained through chromatically different coating materials, can be put onto the market. Thus the user can choose the colour of the voice tube as desired, according to his own aesthetic preference, and reuse it every time he uses a headset shared by other operators, uniquely distinguishing it from other voice tubes.
  • Figure 1 shows a headset, indicated as a whole with reference numeral 1.
  • the headset 1 comprises an elastic headband 2 on which two earpiece elements 3 are assembled.
  • a voice tube 4 is assembled on one of the two earpiece elements to convey voice from the user's mouth to the earpiece element 3.
  • the ends of the elastic headband 2 are mounted telescopically inside a guide 5.
  • the guide 5 is hinged in an intermediate element 8 so that the intermediate element 8 is free to turn around an axis X with respect to the guide.
  • the intermediate element 8 is hinged to a fork 12, so that the fork 12 can turn around an axis Y substantially at right angles to the axis X.
  • the fork 12 supports the earpiece assembly 3.
  • the earpiece assembly 3 comprises an electroacoustic transducer 31 to convert the electrical signal to an acoustic signal which is heard through the earpiece assembly 3.
  • the electroacoustic transducer 31 is inserted in a transducer holder 19 covered by a cover 32 formed by a printed circuit board.
  • a connector 33 with an electrical cable for conveying the electrical signals is assembled on the transducer holder 19.
  • the transducer holder 19 is covered by a foam covering 34 destined to come into contact with the user's ear.
  • the transducer holder 19 is fixed to an annular support 35 which is hinged to the fork 12, so that the annular support 35 can turn around an axis Y' substantially parallel to the axis Y. In this manner the intermediate element 8 and the fork element 12 form a pantograph with respect to the earpiece element 3 which is articulated with respect to the guide 5.
  • the voice tube assembly 4 comprises a hollow tubular element 24 which is assembled to a cover 15.
  • the cover 15 comprises a circular plate 16 provided with a tang 17 which has a hole 18 wherein the hollow tube 24 is engaged by pressure. In this manner, through coupling and uncoupling by pressure, replacement of the voice tube proves extremely simple.
  • a substantially cylindrical cap 23 is inserted in the free end of the tubular element 24 purely for aesthetic purposes.
  • the cover 15 is mounted rotatably on the annular support 35 so that it can turn around the axis Z of the circular plate 16.
  • a spring ring 36 is interposed between the cover 15 and the annular support 35 to regulate rotation of the cover 15. In this manner the tubular element 24 can be regulated so that its end 23 is brought near to the user's mouth.
  • a transducer or microphone 60 able to convert the acoustic signal coming from the tube 24 to an electrical signal which is sent toward the output of the headset.
  • the transducer 60 can clearly be inserted in any part of the earpiece assembly 3.
  • the voice tube 24 is made by coextrusion of a plastic material 70 and a metal core 71.
  • the plastic material 70 is extruded so as to have a hollow tube with an inside diameter of about 1.5 mm and an outside diameter of about 3.5 mm.
  • the metal core 71 is a thin metal wire with a diameter of less than about 2 mm which is coextruded with the plastic material 70 so as to be in an eccentric position and substantially parallel with respect to the axis of the voice tube 24.
  • the metal core 71 is preferably completely covered with plastic material 70 and remains inside the thickness of the tube.
  • the plastic material 70 is a flexible plastic material.
  • a transparent plastic material such as polyethylene, for example, is preferably used.
  • the metal core 71 is made of a substantially rigid metal which can be easily bent and maintain the bent shape.
  • the metal core 71 can preferably be made of steel wire.
  • the voice tube 24 can be bent by the user into any position suitable to bring the end 23 of the voice tube 24 near to the user's mouth and the voice tube 24 maintains said desired position until a subsequent bending.
  • the voice tube 100 comprises a metal coil spring 101 which is wound in a coil so as to form a hollow tube with an outside diameter of about 3.2 mm and an inside diameter of about 1.2 mm.
  • the coil spring 101 is coated on the outside with a layer of malleable metal material 102.
  • the gaps present between the outer surface of the coils of the spring are caused to widen. These widened gaps are filled by the malleable metal material 102 which ensures that the bent position of the coil spring 101 is maintained. In this manner the coil spring 101 can be bent into the desired position and, thanks to the presence of the layer of malleable metal material 102, it maintains this position.
  • the coil spring 101 is preferably made of steel and the layer 102 of bronze.
  • the malleable layer 102 can in turn be coated with a sheath 103 of transparent or coloured plastic material.
  • the coating sheath 103 is preferably made of heat-shrinkable material such as polyolefin.
  • the two ends 105 and 106 of the voice tube 100 are bare so that the end 106 can be inserted by pressure into a hole provided in an earpiece assembly of an acoustic headphone, such as the hole 16 in the tang 17 of the cover 15 according to the first embodiment.
  • the other end 105 of the voice tube 100 can accommodate a cap similar to the cap 23 described in the first embodiment.
  • the voice tube 24 according to the first embodiment and the voice tube 100 according to the second embodiment can in any case be applied to other types of headset having other types of earpiece assemblies, by means of any type of removable assembly, which allows coupling and uncoupling to be achieved simply by the user.
